Despite your newly minted millions, if (when) shit hits the fan, we are way more likely to survive than you and yours. Chances are you wouldn’t make it past the first wave of people looking for food.
One of our homes is smack dab in the middle of a couple thousand acres of farms. We have an orchard. I have irrigation to my planter boxes, from a well, run by solar. While my point that if the factory farmed meat stops flowing, humans will hunt game to extinction still stands, there are deer, quail, wild turkey and wild boar in large numbers in the area - you don't even need a permit to hunt boar as they are invasive species. I don't hunt but if it came to that, they are easy to trap.
Won't matter. Do you have a back store of heart medicine? What's your eyesight like - if it's not 20/20, I really hope you don't break your glasses or contacts. Got any antibiotics lying around? Hmm - that well, we have to bleach it every year or bacteria will make the water undrinkable. The septic system has to be purged every couple of years by a guy with a big truck. Whoops - here comes a fire. Too bad CalFire doesn't exist anymore. Oh you don't live in Fire country - have fun fixing that house now that a tornado knocked a tree down on it. You could have gone to the basement and not had that tornado kill your kid but you didn't know tornadoes were coming because there is no emergency weather alert. By the time you saw it coming, you could have hopped in your car and drove away but you have no gasoline. At least you aren't one of those suckers in Florida that doesn't know a hurricane will be hitting in 2 hours despite the current sunny weather.
Preppers are delusional. If nothing else they'd all commit suicide from boredom.
